Whose approval is required for an individual to obtain their radiation dose records?

Obtaining radiation dose records typically does not require any individual's approval, making this option the correct choice. Radiation dose records are maintained as a part of safety and regulatory compliance within many facilities that handle radiation. These records are essential for ensuring that workers are within safe exposure limits and are often accessible to the individual workers for their review.

This practice aligns with regulations and guidelines aimed at transparency and personal safety in environments where radiation exposure may occur. As a result, individuals can request and review their dose records without needing additional approvals, ensuring they are well-informed about their radiation exposure levels.

The other options suggest a need for approval from specific management levels, which is unnecessary in this case. While a dosimetry manager, department manager, or immediate manager may oversee the radiation safety program and the management of dose records, they do not gate access to an individual's own records, which reflects the fundamental principles of personal rights and safety in workplace health regulations.
